|Behind the scenes information|
The duo are starring in an action movie, where the two frantically try to dodge the oncoming attacks of Ninja Billies, this is primarily the reason Maurie mistakenly thought three times that the stars were under attack by Boss Cass. The first time Ty meets them, it appears that the duo are both running away from Ninja Billies that are assaulting them. When Ty sees that, he promptly attacks the Ninja Billies. After defeating them for the first time, the duo will introduce themselves to Ty, and the director will come in angrily and tell him that the Ninjas were expensive stuntmen, and kicks him out for ruining the movie. The second time, it is a similar situation. But on the third time, the director, Buck Fox, congratulates Ty for being the "hero" in the movie.
- Although they are in no direct threat, Birrel and Squeaver's health meter will lose health if they are attacked by the Ninja Billies
- Birrel has an "American" accent, which can be best described as a "country" accent.
